Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for controlling light modules in motor vehicles are limited by the native resolution, and increasing visual resolution through beam deflection is resource-intensive and time-consuming.
Innovation Solution
A method involving converting a high-resolution setpoint image into two low-resolution images, one of which is recurrently deflected to visually superimpose on itself, utilizing a deflection unit to enhance perceived resolution beyond the native limit, with control parameters determining the duration and frequency of deflection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If beam deflection is used to increase visual resolution, then perceived resolution is improved, but resource consumption and processing time increase
Solution Approach 1:
The patent applies preliminary action by pre-calculating and storing multiple preprocessed images at different resolutions and deflection states before runtime. During operation, the system simply retrieves and displays the appropriate preprocessed image based on current requirements, avoiding real-time complex calculations and reducing resource consumption while maintaining high perceived resolution through selective beam deflection.
2Measurement precision
If beam deflection is used to increase visual resolution, then perceived resolution is improved, but processing time increases
Solution Approach 1:
The system performs image preprocessing and resolution enhancement calculations in advance, storing multiple versions of images at different resolutions and deflection angles. During runtime, the system only needs to retrieve and display the appropriate preprocessed image, dramatically reducing processing time while maintaining high perceived resolution through selective beam deflection.
3Measurement precision
If native resolution is increased to match setpoint image resolution, then image quality is improved, but device complexity and cost increase
Solution Approach 1:
The patent applies dynamics by implementing a dynamic resolution enhancement system that uses beam deflection to temporarily increase the effective resolution of the light module. Instead of using a fixed high-resolution configuration, the system dynamically adjusts the beam direction to display multiple preprocessed images in sequence, creating a perceived higher resolution output from a lower native resolution light module.
Solution Approach 2:
The system introduces an intermediary processing layer that includes a processor for precalculating multiple images at different resolutions and a control unit for selecting and displaying appropriate images. This intermediary layer enables the light module to achieve high image quality without requiring physically complex high-resolution hardware, by mediating between the simple light module and the high-resolution display requirement.
